Cement slurry mixer, this machine is one of the special equipment specified in GB1346-2001. It is a new type of double-rotation and double-speed cement slurry mixer manufactured according to the main technical parameters of GB3350.8-89. Mix the cement and water specified in the standard and stir it into a uniform test slurry, which is used to measure the cement standard consistency, setting time and make stability test blocks. It is suitable for cement plants, construction units, relevant professional colleges and scientific research It is one of the necessary and indispensable equipment in the cement laboratory of the unit. Below we will further understand the relevant knowledge of cement slurry mixer.

Structure and working principle of cement slurry mixer

Structure:

Mainly include two-speed motor, transmission box, main shaft, eccentric seat, mixing blade, and mixing pot , base, column, support, outer cover, programmable controller, etc.

Working principle:

The two-speed motor (1) transmits the power to the worm (3) in the transmission box (10) through the coupling (2) and then through the worm gear (6 ) and a pair of gears (7) and (9) are transmitted to the main shaft (8) and decelerated. The main shaft drives the eccentric seat (12) to rotate synchronously, causing the stirring blade (16) fixed on the eccentric seat (12) to revolve. At the same time, the stirring blade completes the rotation movement around the fixed internal gear (11) through the planetary gear (13) at the upper end of the stirring blade shaft (14). The two-speed motor automatically completes a specified working procedure of slow-stop-fast rotation through time programmable controller control. The mixing pot (17) and the sliding plate (18) are rotationally locked with an eccentric groove.

Cement slurry mixer price

Cement mixers are divided into: cement mortar mixer, cement slurry mixer, cement mortar mixer, etc. The prices range from 2,000 to 5,000 yuan.

Installation method of cement slurry mixer

1. This machine does not have a lifting device and can be transported manually.

2. To install this machine, you only need to place the main unit on a flat cement platform and put a layer of 5~8mm thick rubber plate on the bottom. 3. Power supply and safety grounding. This machine comes with a 2m long power inlet cable and a four-core socket. It is necessary to ensure that the phase line and neutral line are correct before power can be supplied. The insulation of electrical appliances has reached the standard when leaving the factory. In order to ensure the safety of electricity use, please reliably ground the safety ground mark point of the fuselage with a multi-strand plastic copper core wire of no less than 1_2 cross-section

3. Special reminder, because some The internal relays of the controller and host are powered by 220v, so the power cords are three fires and one zero, not three fires and one ground. Do not make mistakes when wiring, and read the instructions carefully before installation. If connected incorrectly, it will not work or may even be dangerous.

Operation and use of cement slurry mixer

Turning the handle (20) can cause the sliding plate (18) to drive the mixing pot to move up and down along the guide rail of the column (21). Move it up and tighten the positioning screw (19) to stir. Remove the mixing pot and do the opposite. When looking down from above, the rotation direction of the blades is clockwise. The direction of revolution is opposite.

First put the three-position switches (1K, 2K) in the stop position, then insert the time controller plug into the "Programmable Input" socket on the panel, and then turn on the power.

Electrical operation is divided into manual and automatic.

Automatic: Turn the switch 1K to the automatic position, which will automatically complete slow stirring for 120 seconds, stop for 10 seconds and then alarm for 5 seconds, and quick stirring. 120 seconds of action, then automatically stops. When an automatic program ends, if you put the 1K switch to stop and then put the 1K switch to automatic, the next automatic program will start again. After each automatic program ends, the 1K switch must be set to stop to prevent the program controller from malfunctioning after a power outage.

1. Automatic: Turn the switch 1K to the automatic position, which will automatically complete the slow stirring for 120 seconds, stop for 10 seconds and then alarm for 5 seconds, and quickly stir for 120 seconds, and then automatically stop. When an automatic program ends, if you put the 1K switch to stop and then put the 1K switch to automatic, the next automatic program will start again. After each automatic program ends, the 1K switch must be set to stop to prevent the program controller from malfunctioning after a power outage.

2. Manual: Turn the switch 1K to the manual position, and then place the three-position switch 2K to the slow, stop, fast, and stop positions to complete each action separately and manually time it.

Note: The three-phase power supply wiring of the socket must ensure that the blade revolution direction is consistent with the direction marked on the body, otherwise the mixing mechanism will be easily damaged.

The electrical operation of the cement slurry mixer is divided into manual and automatic:

Cement slurry mixer operating procedures

1) Before mixing, the mixing pot and mixing Leaves should be wiped clean with a damp cloth first.

2) Pour the weighed sample into the mixing pot.

3) Place the mixing pot on the mixer pot base and raise it to the mixing position.

4) Start the machine and slowly add water to mix. Stir slowly for 120 seconds and stop mixing for 15 seconds. Then stir quickly for 120 seconds and then stop and disconnect the power supply.

5) After the operation is completed, the mixing blade and mixing pot should be cleaned in time

Cement slurry mixer maintenance and upkeep

(1) The working area should be maintained Cleaning: After each use, the residual mortar inside and outside the mixing blade and mixing pot should be thoroughly removed, and the mortar and dirt scattered and splashed on the machine should be cleaned. After wiping it dry, put on a protective cover to prevent dust.

(2) This machine has no external refueling hole. Molybdenum disulfide grease should be added to moving parts such as worm gears, gear sets and bearings in the transmission box once a quarter. When refueling, the bearing covers can be opened separately. Oil should be regularly dripped between the supports and column guide rails, and between the lifting mechanisms. For maintenance once a year, clean the entire machine and add lubricating oil and grease.

(3) If there is metal impact noise when the machine is running, you should first check whether the gap between the mixing blade and the mixing pot is correct.

(4) When using the mixing pot, handle it with care and do not bump it randomly to avoid deformation of the mixing pot.

(5) When replacing a new mixing pot or blade, the gap should be adjusted as mentioned above.

(6) Electrical insulation should be checked frequently. The cold insulation resistance at 20℃±5℃ and relative humidity of 50~70 is ≥5MΩ
